SAFETY INSTRUCTIONS
In order to comply with current European
safety regulations it is essential that the
Naim loudspeaker connectors supplied
with amplifiers and loudspeakers are
used.
Do not under any circumstances
allow anyone to modify your Naim
equipment without first checking with the
factory, your retailer, or your distributor.
Unauthorised modifications will invalidate
your guarantee.
Equipment must not be exposed to
dripping or splashing and no objects
filled with liquid, such as vases, should be
placed on the equipment.
For your own safety do not under any
circumstances open Naim equipment
without first disconnecting it from the
mains.
Warning: an apparatus with CLASS I
construction shall be connected to a
mains socket outlet with a protective
earthing connection.
Where the mains plug or an appliance
coupler is used as the disconnect device,
the disconnect device shall remain
readily operable. To disconnect the
equipment from the mains remove the
mains plug from the mains outlet.
The following label is attached to the
NAPSC:
This equipment has been tested and
found to comply with the relevant EMC
and Safety Standards, and, where

can radiate radio frequency and, if not
installed and used in accordance with
the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that
interference will not occur in a particular
installation. If this equipment does cause
harmful interference to radio or television
reception, which can be determined by
turning off and on, the user is encouraged
to try to correct the interference by one or
more of the following measures:
Reorient or relocate the receiving
antenna.
Increase the separation between the
equipment and the receiver.
Connect the equipment into an outlet
on a circuit different from that to which
the receiver is connected.
Consult your Naim retailer or an
experienced radio/TV technician for
help.

Naim Audio products are conceived with
performance as the top priority. Careful
installation will help ensure that their full
potential is achieved. This manual covers
the NAPSC and i-Supply power supplies,
Headline headphone amplifier and Stageline
phono amplifier. It begins with general
installation notes and statutory safety
warnings. Product specific information
begins in Section 5.
1 Connections
It is important for both safety and
performance that any standard cables
supplied are not modified.
1.1 Analogue Audio
Interconnect Cables
If options are available with your equipment
and installation, DIN interconnect sockets
should be used in preference to Phono
sockets. One end of each Naim audio
interconnect cable is marked with a band
to establish its correct orientation. The band
denotes the end that connects to the signal
source. Naim Hi-Line interconnect cables will
provide the best results.
Audio interconnect plugs and sockets should
be kept clean and free from corrosion. The
easiest way to clean them is to switch off
the equipment, pull the plugs out of their
sockets, and push them back in again.
Contact cleaners and “enhancers” should
not be used as the film they deposit may
degrade the sound.
2 Mains Power
Where fused plugs are used 13 amp fuses
should be fitted (i-Supply 3 amp). Fuses of
a lower rating will fail after a period of use.
Do not wire voltage dependent resistors or
noise suppressors into mains plugs. They
degrade the mains supply and the sound.
2.1 Mains Plug Wiring
In some territories a mains plug may need to
be fitted to the supplied mains lead. As the
colours of the wires in the mains lead may
not correspond with the coloured markings
identifying the terminals in the plug proceed
as follows:
The wire coloured GREEN and YELLOW must
be connected to the terminal in the plug
marked by the letter E or by the safety earth
symbol or coloured GREEN or GREEN and
YELLOW.
The wire coloured BLUE must be connected
to the terminal in the plug marked with the
letter N or coloured BLACK.
The wire coloured BROWN must be
connected to the terminal in the plug
marked with the letter L or coloured RED.
2.2 Equipment Fuses
Mains powered Naim Audio equipment is
fitted with a mains fuse on the rear panel
adjacent to the mains input socket (not
i-Supply). Replace it if necessary only with
the spare fuse supplied or with an identical
fuse. Repeated failure of the fuse points to
a fault that should be investigated by your
retailer or Naim Audio.
2.3 Non-rewirable Mains
Plugs
If a non-rewirable plug is cut from a mains
lead (for whatever purpose) the plug MUST
be disposed of in a way to render it totally
useless. Considerable shock hazard exists
if the cut-off plug is inserted into a mains
outlet.
2.4 Mains Circuits and
Cables
A hi-fi system usually shares a mains circuit
with other household equipment, some of
which can cause distortion of the mains
Accessories
2
waveform. This distortion can in turn lead to
mechanical hum from mains transformers.
Some Naim transformers are large in size,
making them relatively sensitive to such
distortion, and it may be necessary to take
account of transformer hum when siting your
equipment.
Transformer hum is not transmitted through
the speakers and has no effect on the
performance of the system; however, a
separate mains circuit may reduce it. Such a
circuit (ideally with a 30 or 45 Amp rating) will
also generally improve system performance.
Advice on the installation of a separate
mains circuit should be sought from a
qualified electrician.
Use only the mains leads and plugs supplied
or the Naim Power-Line mains cable.
3 General Installation
Naim equipment is designed to offer the
finest performance possible avoiding
compromise wherever practical. This
can lead to circumstances that may be
unfamiliar. The notes that follow contain
advice specifically related to Naim
equipment as well as more general
warnings about the use of domestic audio
products. Please read them carefully.
3.1 Siting The Equipment
In order to reduce the risk of hum audible
from the loudspeakers, power supplies
and power amplifiers should be located
a reasonable distance away from other
equipment. The maximum separation
distance for connected equipment is that
allowed by the standard interconnect lead.
Some Naim equipment is extremely heavy.
Check the weight of the equipment prior
to lifting and if necessary use more than
one person so that it can be moved safely.
Ensure that your equipment rack or table
can easily support the weight and is stable.
3.2 Switching On
Source components and power supplies
should be switched on before power
amplifiers. Always switch amplifiers off
and wait a minute before connecting or
disconnecting any leads. Always use the
power switch on the product rather than a
mains outlet switch.
A “thump” may be heard from the
loudspeakers as power amplifiers are
switched on. This is normal, will not cause
any loudspeaker damage and does not
point to any fault or problem. A mild “pop”
may also be heard shortly after equipment is
switched off.
3.3 Running In
Naim equipment takes a considerable time
to run in before it performs at its best. The
duration varies, but under some conditions
the sound may continue to improve for
over a month. Better and more consistent
performance will be achieved if the system
is left switched on for long periods. It is worth
remembering however that equipment left
connected to the mains can be damaged
by lightning.
3.4 Radio Interference
In some circumstances, depending
on where you live and the earthing
arrangements in your home, you may
experience radio frequency interference.
Controls on broadcasting in some territories
allow very high levels of radio frequency
radiation and both the choice and exact
siting of equipment may be critical.
Susceptibility to radio frequency interference
is related to the wide internal bandwidth
necessary for high sound quality. A radio
frequency filter kit is available for some
Naim equipment but sound quality will
be progressively compromised as more
elements of the kit are fitted. In situations of
Accessories

extreme radio interference Naim equipment
may be unsuitable.
3.5 Lightning Precautions
Your Naim hi-fi system can be damaged
by lightning and should be turned off and
disconnected from the mains when there is
risk of lightning. For complete protection all
mains plugs and any aerial cables should be
disconnected when not in use.
3.6 Problems?
Consumer protection varies from country
to country. In most territories a retailer must
be prepared to take back any equipment
he has sold if it cannot be made to work
satisfactorily. A problem may be due to a
fault in the system or its installation so it is
essential to make full use of your dealer’s
diagnostic skills. Please contact your local
distributor, or Naim Audio directly, if any
difficulties cannot be resolved.
Some Naim equipment is made in special
versions for different territories and this makes
it impracticable to arrange international
guarantees. Please establish the local
guarantee arrangements with your retailer.
Contact Naim Audio directly for help and
advice if necessary.
3.7 Service and Updates
It is essential that repairs and updates are
only carried out by an authorised Naim
retailer or at the Naim Audio factory. Many
components are custom made, tested or
matched and appropriate replacements
are often unobtainable from other sources.
Direct contact to Naim for service or update
